Exposure to UV radiation and risk of Hodgkin lymphoma: A pooled analysis
2013
Ultraviolet radiation (UVR) exposure has been inversely associated with Hodgkin lymphoma (HL) risk, but only inconsistently, only in a few studies, and without attention to HL heterogeneity. We conducted a pooled analysis of HL risk focusing on type and timing of UVR exposure and on disease subtypes by age, histology, and tumor-cell Epstein-Barr virus (EBV) status. Four case-control studies contributed 1320HLcasesand 6381 controls. We estimated lifetime, adulthood, and childhood UVR exposure and history of sunburn and sunlamp use. We used 2-stage estimation with mixed-effects models and weighted pooled effect estimates by inverse marginal variances. We observed statistically significant inv…

Divinyl Sulfone Cross-Linked Hyperpolymeric Human Haemoglobin as an Artificial Oxygen Carrier in Anaesthetized Spontaneously Breathing Rats
1994
Hyperpolymeric haemoglobin in concentrations necessary to transport oxygen in organism to a significant extent exhibits a negligible oncotic pressure as compared to that of plasma. This property makes hyperpolymeric haemoglobins suitable for development of an artificial oxygen transporting blood additive. With such an additive - in contrast to an oxygen transporting plasma expander - combating a chronic oxygen deficit of tissue (brain, heart, kidney, extremities or in case of anaemia) is possible. Using in these cases an isoncotic oxygen carrying plasma expander instead of an additive would be even more detrimental because of fluid load to heart, at least in case of heart injury. Chronic ox…
Big Data in Emergency Management: Exploitation Techniques for Social and Mobile Data
2020
The Internet of Things, crowdsourcing, social media, public authorities, and other sources generate bigger and bigger data sets. Big and open data offers many benefits for emergency management, but also pose new challenges. This chapter will review the sources of big data and their characteristics. We then discuss potential benefits of big data for emergency management along with the technological and societal challenges it poses. We review central technologies for big-data storage and processing in general, before presenting the Spark big-data engine in more detail. Finally, we review ethical and societal threats that big data pose.
Toward Unified Control of Networks of Switches and Sensors Through a Network Operating System
2018
Wireless sensor networks (WSNs) are an integral part of an Internet of Things (IoT) ecosystem. In fact, a typical IoT service deployment considers an integrated network of switches and sensors (as well as actuators). In order to manage this heterogeneous network infrastructure, the use of software defined networking (SDN) technologies is anticipated. However, existing SDN-enabling technologies consider only isolated networks and there has been no concrete solution that treats the whole network in a unified way. In this paper, a network operating system is proposed as a way to address the above issue. Starting from the open network operating system, which currently supports only OpenFlow net…
Care research and disability studies: Nothing in common?
2009
Disability researchers have voiced the criticism that the concept of care, together with research based on it, consists of the view that disabled people are dependent non-autonomous second-class citizens. The perspectives of disability studies and care research certainly are different from each other. Disability studies analyse the oppression and exclusion of disabled people and emphasize that disabled people need human rights and control over their own lives. Care research focuses rather on care relationships, informal and formal care, care-giving work and `an ethics of care'. Nevertheless, it is suggested here that the two perspectives are not mutually exclusive and that the two groups co…
How does the online service level influence consumers’ purchase intentions before a transaction? A formative approach
2016
AbstractThe present paper tries to study the impact of online services level in contexts where transactions have not been done yet, through the adoption of a formative approach. In this scene, the present research considers two main dimensions of online services (pre-purchase services and transaction-related services) in a context of clothing purchasing process. Before defining the research and determining the sector to be analyzed, 7 focus groups were conducted. From the obtained conclusions, this study was carried on in the textile sector. A survey with 370 effective respondents was carried out. To measure the different concepts in the model, several scales were used based on literature p…
Self-discrepancy and impulse buying: an exploratory study
2008
Nowadays, consumer behavior is more sophisticated and complex than before. In this study, I attempt to analyze the relationship between impulse buying (consumerʼs emotional side of the consumption) and an individualʼs self-discrepancy (the difference between what one is and what one would like to be). I propose that a consumer uses impulse buying to lift oneʼs self up and remove oneʼs self-discrepancy. Results from a sample of consumers in Spain established that a consumer experienced self-discrepancy was likely to have impulse buying. Moreover, the larger the self discrepancy, the more one was dissatisfied with oneʼs consumption. Finally, symbolic meanings of products to the consumer were …
Nordic subsidiaries in the Baltic States: is model transfer possible?
2011
PurposeThis research seeks to ask to what extent model transfer in employee relations (in terms of employee representation, participation and workplace bargaining) occurs between Nordic and Baltic countries from the principal firm to the subsidiary. It also looks into explanations as to why model transfer occurs – or does not occur – from the perspective of the Nordic industrialist's labour management strategy.Design/methodology/approachThis is a case study comprising three clothing manufacturers and three engineering shops in different Baltic States: Estonia (population 1.4 million), Latvia (2.3 million) and Lithuania (3.4 million). These production sites have headquarters in three Nordic …
